This time, Tiger has bought a $60 million secondary stake in the company behind WordPress.com. San Francisco-based investment company Iconiq Capital also picked up $15 million in shares.

Together, the firms bought most of a stake owned by Polaris Venture Partners, one of Automattic’s early venture capital backers.

WordPress co-founder Matt Mullenweg posted on his personal blog that up until now Polaris had been Automattic’s largest investor and second largest shareholder.

WordPress co-founder Matt Mullenweg has announced Tiger Global has thrown another $50 million at Automattic.

“(Former Polaris partner) Mike Hirshland wrote the biggest checks in our 2006 and 2008 rounds (the only primary capital Automattic has raised) and served on our board until 2011 when he left the firm,” Mullenweg said.

“Although they’ll no longer be on the board, Polaris will continue to be a major shareholder, retaining about a third of their stake.

“Now that Automattic has been locked in as a win for their portfolio, I hope they’ll continue to be involved for many years to come.

“I’m glad to be even more fully aligned with Tiger. I think it says a lot to their excitement in the company that just a few months after joining the family and learning more about the company they significantly increased their stake, and at a significant bump in valuation.”
